1.	Radius of corved path is r and the coefficient of friction between the wheel of a car and that path is mu. What should be the maximum speed with which the car can take a turn without skidding in that curved path?
Answer» Solution :Weight of the car = mg , so normal force OFFERED by the path = mg. Hence. LIMITING frictional force = `MU`mg. [ `mu` = coefficient of friction between the wheel of the car and the path ] The limiting frictional force provides the centripetal force necessary to prevent SKIDDING. so, if the maximum speed of the car is v, then the condition for no skidding in that path is, ` (mv^(2))/(r) = mu mg " " or, " " v = sqrt(mu r g ).`
